hi i just started on this site and got referred to this area.
i am 5' 10" 230 lbs. i am not really that fat, 35" waist just a pretty muscular guy who wants to ride to get in a bit better shape. i don't think i have ever been lighter than 215 my entire adult life.
i started riding last summer with some guys from work. they all have road bikes and i am riding a trek 730 muktitrek. i logged about 600 miles last summer.
i always seem to be at the back of the pack, or they have to slow up so i don't fall to far back, because of poor gearing, only 50 teeth front crank with a smallest of 12 on the cassette.
i just picked up a trek 2300 composite bike at a thrift shop cheap that needed some work.
after purchasing the repair parts to recondition it. a co worker mentions that i might be a bit heavy for the carbon fiber on the 2300. the final gearing would be 53 crank, 11 on the smallest on the cassette.
is he pulling my chain hoping i won't ride my better bike and keep up with him, maybe even be faster than him with better gearing? or does he have a point that due to my size i might over stress the carbon fiber on the 2300.
maybe just put better gearing and road tires on the 720 and call it a day. then sell the 2300 for a fair profit.
what are your thoughts on this subject?
